Abstract

The utility model relates to a grinding machine with planets oscillation for grinding granite stones, which comprises a planetary transmission mechanism and a mechanism capable of enabling a grinding block to swing and adopts mechanical parts such as a cam, a slide block, a chute and a connecting rod to make the grinding block rotate with a grinding head simultaneously and autorotate and swing. The smoothness and the glossiness of the grinding processing of the granite boards can reach or exceed the products produced by an import production line. The productive efficiency is high, the board breakage rate is low, the energy consumption is small, and the construction investment is low. The grinding machine with planets oscillation for grinding granite stones is completely domestically produced and is a grinding machine with outstanding performance for the production of granite boards, in particular for the production of thin boards.

Description

Grinding machine with planets oscillation for grinding granite bloke

The utility model belongs to the abrasive machine field of processing of stone.

At present, the grinding machinery of processing granite in slab adopts the plane abrading block to carry out grinding more.Because it is hard frangible that granite has, add the poor reliability of abrasive machine work, and some other problems, cause of poor quality in the granite in slab processing industry, efficient is low and problem such as production cost height can not finely solve all the time.Though the external existing technology that adopts the swing abrading block is quoted on homemade grinding machine as yet.The granite in slab grinder (patent No. 88209700.8) of this research institute invention has at first adopted the swing abrading block, abrading block is changed into line contact processing to the plane contact processing of stone material, having solved the grinding machine gross pressure effectively can not be too high and but the have relatively high expectations contradiction of pressure of machined surface, granite in slab flatness, glossiness and the volume recovery produced all are significantly improved, and its production efficiency uses general homemade grinding machine to be five times, ten times raisings, and grinding machine manufacturing cost and sheet material processing cost but descend significantly.But a weak point of this machine is can only be applicable to polish earlier sheet material (mainly being that thickness is 20 millimeters the on-gauge plate) processing of afterwards cutting edge.Good, superior in quality but natural crack is many, cause the little granite mineral products of waste material volume in order to make full use of a large amount of patterns of China, also in order to export goods and earn foreign currency, satisfy the needs of world market, we must develop the production of granite light sheet (for example thickness is 10 millimeters plate, and the larger area thin plate is especially arranged) simultaneously.In recent years from some thin plate production lines of external introducing, these production lines adopt planet grinding head more, each abrading block also produces rotation in the bistrique rotation, make abrading block and processing of stone face contact and wearing and tearing that abrading block takes place are all compared evenly, and can be ground to the edge of sheet material, that is to say the specification hair plates that can grinding have cut finished size, but because its cutting power is low, article one, production line wants a lot of roads (for example 14～16 roads) bistrique just can go out finished product, it is high to build required investment, every cover production line cost is very high, and product glossiness do not reach requirement toward contact, and operating repairs are also very difficult.

It is strong that the purpose of this utility model is to invent a kind of grinding capacity, and production efficiency height, volume recovery height, good product quality, equipment manufacturing cost and sheet material production cost are all low, the granite sheet grinder tool of being convenient to Operation and maintenance and domesticizing fully.

The utility model is realized its purpose with following structure: differential gear makes the interior axle of bistrique rotate with different speed with outer shaft, and outer shaft drives the bistrique case and rotates, and interior axle drives one group of sun planetary bevel gear and one group of sun planet roller gear rotation.After power imports differential gear housing into, begin to rotate simultaneously at the bistrique case, the planet roller gear drives the rotation of abrading block case, make abrading block constantly rotation thereupon, and planetary bevel gear makes the eccentric wheel that is fastened on the planetary bevel gear axle by connecting rod the slide block in the abrading block case be moved up and down, and the rotation by shift fork makes abrading block revolve round the sun, swing in the rotation; So just realized that three kinds of motions take place simultaneously, guaranteed high-quality, high efficiency and the low consumption of granite in slab grinding, reached the purpose of this utility model satisfactorily.This granite grinding mill can grind the big thin plate that cuts specification, and (as 600 * 900 * 10mm), the side cut hair plates that can grind standard specification again is (as 600 * 900 * 20mm).

Further specify the utility model below in conjunction with accompanying drawing:

Fig. 1 is the schematic diagram of this planet swing bistrique granite grinding mill.

Behind power input differential case 1, axle 5 and outer shaft 4 rotations in gear mesh 2 and gear mesh 3 drive respectively; Outer shaft 4 makes the 6 whole rotations of bistrique case, and abrading block 23 revolves round the sun thereupon; Interior axle 4 drives parasol gears 12 and 16 rotations of sun roller gear; After roller gear 16 reaches 4 planetary gears 15 with power, the cylindrical planetary gear axle 14 of hollow drives abrading block swing case 17 and abrading block 23 rotations that connect with its tight fit, meanwhile, parasol gear 12 is passed to power on the planetary bevel gear axle 9 of four planetary bevel gears 10 and four strap cams, the slide block 8 that wraps in the cam outside is done level or translation vertically with the rotation of cam, when it does level to translation, can only be in slideway 7 move left and right in the dead space of enclosing of horizontal positioned; When it does vertically to translation, force slideway 7 integral body in the vertical direction translation, because slideway 7 is fixed on the bearing block 11, bearing block 11 also has only is being with connecting rod 13 to do vertically to move up and down, and with its fastening little axle that links to each other 18 by the vertical moving belt of connecting rod 13 and to move up and down, it be center of circle rotation with swinging axle 21 that the slide block 19 that wraps in little axle 18 outsides just forces shift fork 20, because of the swing arm 22 that connects abrading block 23 is fastenedly connected with swinging axle 21, therefore, connecting rod 13 moves both vertically that to cause abrading block 23 be that constantly swing in the center of circle with swinging axle 21.

Adopt the thin plate production line of the utility model grinder, only need to use 8 bistriques and corresponding conveyer belt, just the import production line be can reach and output and the quality requirement of 14～16 bistriques wanted, and can use the littler hair plates of size, make the sheet material breakage rate very low, and its capital construction investment and sheet material production cost are more much lower than import production line.
